OVER SPEC The power supplies are using more power than their maximum rating. NMI A nonmaskable interrupt has occurred, or the NMI button has been pressed. If the system-error LED is lit, it indicates that an error has occurred; go to step 2. Buy the Full Version You're Reading a Free Preview Pages 109 to 202 are not shown in this preview.

Error A software NMI has occurred. Reseat the hard disk drive backplane. It is also found on almost every linux boot disc, Live CD or install CD - just type "memtest" or "memtest86" at the prompt. And at that point, the power's-going-to-die NMI may not matter much. (But I'm not sure whether it matters or not: when power fails and the NMI is generated, what should the

See System-board switches and jumpers for the location of the SW4 switch block on the system board. All rights reserved. Thus 200 means the system memory was tested. The codes that I am presenting here are from documents I have read through, found on the web, found in old books, documents and technical papers.

BRD An error has occurred on the system board. If the error remains, replace the following components in the order listed, restarting the server after each: Replace the hard disk drive (see Removing a hot-swap hard disk drive for more Important: Some cluster solutions require specific code levels or coordinated code updates. Spire says: February 27, 2007 at 4:18 pm I have an somewhat related question (not necessarily directed at Raymond, but to anyone reading who might know the answer).

An error has occurred and cannot be diagnosed, or the IMM has failed. Complete the following steps to correct the problem: Update the server firmware to the latest level. The comment was that one some DRAM, the chips power up with random data. LOG An error occurred.

Richard says: February 27, 2007 at 8:31 pm I just found a very dusty book on my shelf titled "Professional Debug Facility" from IBM. Replace any failing device. (Trained service technician only) Replace the system board. They will just suddenly reboot. Mark Hampton says: February 28, 2007 at 11:14 am I found another way to generate NMI's by accident… In college, a roommate and I built a plugin card (etched the card

Experts Exchange Miscellaneous How to track your lost Android Phone? My colleague Keith Moore reminded me that paradoxically, on the IBM PC-AT, you could mask the non-maskable interrupt! By placing the system-error LED indicator in Remind mode, you acknowledge that you are aware of the last failure but will not take immediate action to correct the problem. If the problem remains, go to the "Before you call IBM Service" website.

Luckily, I had one, and we piggy backed it on the bad one and replaced the blown one. Check the system-event log in the Setup utility or IMM error messages. I once had one clear the screen and inform me that the system bus had failed. Not sure why ‘several times' though, maybe it's something to do with refreshing.

If the CNFG LED is lit, then an invalid microprocessor configuration has occurred. If the CNFG LED and the CPU LED are lit, complete the following steps to correct the problem: Check the microprocessors that were just installed to make sure that they are CPU When only the CPU LED is lit, a microprocessor has failed. Make sure that the microprocessors are compatible with each other.

If you pressed it, the card generated an NMI. Press this button to force a nonmaskable interrupt to the microprocessor. Use the Setup utility to check the system-event log for information about the error. No fumbling around with ball-point pens for these folks, no-ho! (To be honest, I had two of these.

Make sure that both power supplies installed in the server are of the same type. The following illustration shows the light path diagnostics panel:Figure 2. But I've always wondered what would happen if one did. No action; information only.

Check the power-supply that has an lit amber LED (see Power-supply LEDs). OK, I won't complain too loudly about watchdogs. Error An operator information panel NMI/diagnostic interrupt has occurred. PS Power supply 1 or 2 has failed.

Check the device driver. 2. PCI An error has occurred on a PCI bus or on the system board. Make sure that the room temperature is not too high. Does an NMI still get generated, like in the old days?

Replace a failing power supply. For more information, go to the "Before you call IBM Service" website. When an error occurs, LEDs are lit throughout the server. You might have to use a pen or the end of a straightened paper clip to press the button.
